Background/Aims:Bowel preparation for colonoscopy remains an unpleasant experience because oral solutions have unpleasant tastes and may provoke abdominal pain, nausea, vomiting, and sleep disturbance. Duodenoscopic bowel preparation is an alternative method for patients who are unwilling to take oral preparation solution or for those who are supposed to have both gastroscopic and colonoscopic examination on the same day. We assessed the effectiveness and tolerance of duodenoscopic bowel preparation.
Methods:Patients in group OA (orally administered) ingested 45 mL of sodium phosphate (NaP) in the evening before the day of procedure and in the morning on the day of colonoscopy, whereas patients in group EA (endoscopically administered) were prepared for the procedure by duodenoscopic infusion of 90 mL of NaP diluted with 180 mL of water into the second portion of the duodenum. After 4 hours, we assessed the overall quality of colonic cleansing, using a range of excellent to inadequate. The patients completed a questionnaire on their preparation-associated symptoms, tolerance, and preference.
Results:In group EA, sleep disturbance (p＜0.05) and nausea (p＜0.05) occurred less frequently than in group OA. Overall, the tolerance rating for preparation was higher in group EA. However, the quality of colonic cleansing and cecum intubation time was not different between the two groups. Patients in group EA who had ingested NaP in the past preferred duodenoscopic bowel preparation.
Conclusions:Duodenoscopic bowel preparation may play a role in colonic cleansing especially for patients who are scheduled to undergo gastroscopic and colonoscopic examination on the same day and for those who are unwilling to ingest NaP. (Korean J Gastroenterol 2007;50:78-83)
